Zusammenfassung:A copper-coated steel wire includes a core wire made of a stainless steel, and a coating layer made of copper or a copper alloy and covering an outer peripheral surface of the core wire. In a cross section perpendicular to a longitudinal direction of the core wire, the outer peripheral surface of the core wire has a value of an arithmetic mean roughness Ra of not less than 25% and not more than 90% of a thickness of the coating layer.
